Plasma N-Terminal Pro-Brain Natriuretic Peptide as a Marker of Right Ventricular Dysfunction in Patients With Tetralogy of Fallot After Surgical Repair

RV dysfunction detected by echocardiography and plasma NT-proBNP determination in asymptomatic or minimally symptomatic TOF patients correlates well with their cardiopulmonary exercise capacity. Thus, these simple and noninvasive screening methods can be used additionally to stratify ACHD patients with impaired cardiac function before they become clinically symptomatic.
